RESUMEN
Background: The aim of this study is to evaluate the relationship between sperm parameters and body mass index [BMI] in the male spouses with infertility complaints, who had reffered to our clinic
Materials and Methods: The male spouses from 159 couples reffering to our clinic because of infertility, during a six-month period, were included in the study. In this prospective case control study, the included men were categorized as non-obese [BMI<25 kg/m[2]], overweight [BMI 25-29 kg/m[2]] and obese [BMI >/= 30 kg/m[2]] according to their BMIs. The assessed sperm parameters consisted of; sperm concentration, Kruger morphology, progressive motility level, and volume pH levels. The statistical significant level was set as less than 0.05
Results: The assessed group consisted of 159 patients applying to our clinic with infertility symptoms. Fifty-three non-obese, 53 overweight and 53 obese men were eligible for the study. There was statistically significant differences in sperm volume [P<0.001], progressive motility [P<0.001], post wash sperm count [P<0.001] and Kruger [P<0.001] morphology among the patient groups grouping according to the BMI levels
Conclusion: In this study, increased BMI was associated with decreased semen quality, affecting volume, concentration, and motility. further studies with a wider range of prospective cases need to be conducted in order to investigate the effects on male fertility in more detail
